To all whom/it infn/y concern: Be it known that I, JAMES V. WAsHBUnNE,

orfS` acuse inthecounty of Ononda a, in

` the tate ofA New `York, have invente new and exact description.

and useful Improvements in Radiators, of

which the'following, taken in connection with the accompanying drawings, is a full, clear,

This invention relates to steam and hot-Waterradiators for t e pur- `pose of controlling the circulation of steam or ot water, so as to cause it to pass either throu h the entire extent of the radiator or only t ough a ortion thereof, and thus vary the radiation o heat in accordancewith the different temperatures desired to be derived l from the radiator.

The object of the invention is 'to attain the aforesaid effect by simple, convenient, and ef- Vend viewof the radiator.

iicient means which are readily applied to .a

radiator of the class in'which the radiator is- `composed of a series of separate loops communicating directly with each other at their lower ends; and to that end the invention consists in the novel construction and combination of partsvhereinafter described, and as illustrated in the accompanying drawings, 'in which- Figures 1 and 2 are front elevationsof radiators embodying my invention. Fig. 3 is an larged detached face view of the cut-ofi valve. Fig. 5 is a transverse section on the line X X in Fig. 4. Fig. 6 shows a modification of Fig.

5. Fig. 7 is an enlarged front view of the connection of the cut-ofl valve to theradiatorloops shown partlyin section, and Fig. 8 is a sectional detail view of the cut-ofi` valve.

` The cut-oil valve shown in the lasttwo iigures is deprived of the air-vent and is designed to beused on radiators which have the usual automatic vent attached to :the top of the radiator, as shown in Fig. 2--of the draw- 'in s. l

c for controlling the infi ux of the steam or hot water. y

`Each ofthe intermediate loops a a is provided in opposite sides of its lower end with ports d, by which it .communicates with the adjacent loops. Each port is surrounded by an annular external face e to form a closelyfitting seatfor a collar j, which is interposed between the ports of two adjacent loops a, a

and is provided with nipples g g, which 'are inserted into said ports and form tubular couplingsleading from port to port. Said nipples Vmay be formed integral with the collar, as represented in Fig. 6 of the drawings, or formed of protruding ends of a tube passing through the collar, as shown in Fig. 5 of the drawings.

h represents the cut-0H valve, which is of the form of. a disk, located between the inner ends of the two nipples g gand closes on semicircular seats 'i i on the interior of the tube.

h is the valve-stem, which is detachably secured diametrically across the disk valve h, and pivoted at one end in: a socket k, formed in the collar f, and passes with its o posite end through the collar' and througha s eeve l, screwed into a socket Z in a boss k', formed on the exterior of the collar. A suitableV handle m is attached 'to the outer end of the valvestem for movingatfhe valve` to and froml its closing position. I preferably bifurcate the inner end portion of the valve-stem and in- "sert the disk valve h in the bifurcation and fasten it to the stem by means of a removable in n passing transversely through said parts. he object of said detachable connection of the valve to itsstem is to allow the valvestem to be withdrawn from the valve when the latter requires repairs or renewal.

stem, I attach thereto a laterally-projecting lug or in o, adjacent to the outer ends of the sleeve and covered by a cap p, screwed onto `the said sleeve, as shown in Fig. 8 of the drawings. To guard against excessive torsional strain on thevalve-stem and at the same time enable a person to ascertain the position of the valve h, I provide the boss le" with two stud-pins i" r or other suitable stops and attach to the outer end of the valve-stem a detent s, which comes in contact with the said stops in turning the valve to its open and closed positions.

C re resents a suitably-constructed ventvalvel or escape of air entrapped in the radi- To' `prevent accidental withdrawal of the valveator. 'lhe case of this valve is attached to i lar and into the ports, a disk valve disposed 55 the collar f in a suitable position to afford ready access to said valve, which communicates with the interior of the nipple-tube through a channel t, extending through the collar f and through the side of the tube g, which may be either integral with the collar f, as shown in Fig. 6, or consist of a separate piece, as shown in Fig. 5 of the drawings, which is a transverse section of Fig. 4. I do not, however, limit myself to the use of the vent-valve C yconstructed and applied as aforesaid, inasmuch as the usual and wellknown vent-valve C may be attached to the loop a, as shown in Fig. 2 of the drawings.

'lhe salient feature of the invention consists in the combination, with the series of loops communicating with each other through tubular couplin s detachably connecting said loo s, of a simi ar coupling interchangeable wit the other couplings and a cut-olf valve in said interchangeable coupling, thus allowing the radiator to be divided into sections of desired proportion.

at I claim as my invention is- 1. A radiator composed of aseries of loops provided with corresponding orts, tubular couplings detachably connected) to said ports, a similar coupling interchan eable with the other couplings, and a cut-o valve disposed in the said interchangeable coupling as set forth.

2. The combination with two-adjacent ra- BJI - diator-loops communicatin with eachother through ports in the sides t ereof, of a collar interposed between the loops and provided with nipples inserted in the orts, and a cutoff valve disposed in said co lar as set forth.

3. The combination with two adjacent radiator-loops communicating with each other through ports in the sides thereof and provided with annular external faces surrounding the orts, of an interposed collar seated on said aces, a tube passing through the collar and into the ports, and a cut-off valve disposed in the tube central of the plane of the collar and having the valve stern passing through said collar as set forth and shown.

4. The combination with two adjacent radiator-loops communicating with each other through ports in the sides thereof, and provided with annular external faces surrounding the orts, of an interposed collar seated on said aces, a tube passing through the co1- in said tube, semicircular valve-seats on the interior of the tube at opposite sides of the disk valve, the valve-stem secured diametrically across said disk valve and pivoted to the collar and having one end extending through the collar and rovided with means for turning it as set forth).

5. The combination with two radiatorloops disposed side b side and communicating with each other t ou h ports in the sides thereof and provided wit annular external faces surrounding the ports, an interposed collar seated on said faces, a tube passing through the collar and into the ports, a disk valve disposed in said tube central of the plane of the collar, a bifurcated valve-stem embracing the valve diametrically and dctachably secured thereto, one end of' said valve-stem pivoted in the aforesaid collar and the o posite end extending through the collar, a s eeve secured to the collar and embracin the valve.- stem, a lug projecting from t e side of the valve-stem at 'the outer end of the sleeve, and a cap connected to the sleeve, said cap and sleeve receiving between them the aforesaid lug as and for the purpose set forth.

6. The combination with two adjacent radiator-loops communicatin with each other through ports in the sides t ereof, of a collar interposed between the ports and provided with nipples inserted into said ports, a cut-off valve between said nipples and having the valve-stem extending radially through the aforesaid collar, anda vent-valve attached to said collar and communicating with the interior of one of the nipples as set forth and shown.

7. The combination with two adjacent radiator-loops communicating with each other through ports in the sides of the loops, a collar interposed between the ports, a tube extending through said collar and into the ports, a disk valve in the tube and having its stem extending radially through the collar, a detent attached to the valve-stem, and sto s on the' collar limiting the movement of t e detent as and for the purpose set forth.
